I thought this was correct

still a big brushless motor!

Google agrees. 50 kw = 67.0511 horsepower.

+1 you are absolutely correct! How can you get the numbers mixed up? 150bhp is over 110 kw.

Standard of the world....


1 hp = 746 watts.

50,000w (50kw) / 746 = 67.02 hp

many408 called it right.

And.........


80mm thick = about 3-1/8"

202mm dia. = about 8" diameter



3" by 8", and 67 hp?????

I'm smelling a whole lot of horsepucky here........

Yes this is the rating means nothing without knowing the voltage that it produces the 150bhp 200bhp at ? yes direct KW power do correspond to 67hp at 50kw we soply no voltage value so motor is more powerful and can be coupled together! 300bhp!!!! we are hoping for 44v @ 112kw! This is new designed motor currently going threw testing Halabatch array and regular config , once we are done we will release data ! yes $2000USD give or take if it performs as expected!
OEM welcome! Exmpe of 5kw motor so you can understand http://offthegridsun.com/Brushless-M...5000B-For-Bike

Yes this is the rating means nothing without knowing the voltage that it produces 50KW at! this conservative value at 22V this motor is capable of lot more voltage! Similar motor here

Very lofty claims, here. How about showing us some real-world data? Your new reference - the 30cm x 30cm x 25cm motor you linked - is roughly 12" x 12" x 10"; it is nearly 10 times bigger than your 8" dia. motor, and carries a max rating of 50kw (which is also terribly suspect, given its mass).

Please, do provide some verifiable data to support these claims.

actually my claims are not lofty ! they are conservative there are simulator motors with 400bhp and cost $20k USD! simular core size! real difference is cooling. if you look at the stats from 5kw motor you can have an idea of what to expect Horse power wise comped to KWH in real world ! when we have the data on this motor I will publish.

I think....


We are going around in circles here.

Another reference to a motor, now only twice the size of the claimed 50kw, that has 1/10 the rated output.

And. I beg to differ; your claims are indeed lofty, in the absence of any kind of tangible data. 400 hp inductance motors exist - Tesla sells them every day. They are, however, considerably larger than 20 cm or 30cm in basic dimension. And are driven by an ample array (to put it mildly) of batteries.

Yes, voltage matters. Yes, cooling matters. Yes, construction matters. In this day and age, it becomes more and more likely that a viable electric motor will produce in excess of 8-10hp/lb.

But so far, we ain't there yet. Not, at least, that anyone has proven. Claims notwithstanding.

Yes we sell those 20K USD motors as well ! your not getting it @ 120V we are hoping for 150BHP ! the core of the motor is the secret sauce, around the same diameter, they just combine stator core's for more BHP , it makes the motor thicker and the housing around it is specialized for liqud cooling oil , water or air. those tesla motors are smaller than you think same with BMW motors! here are the specs for a smaller 40kw motor
Large scale 40kw Brushless out runner motor for plane
The spec as following:
MOTOR: S-154120 KV55
KV: 25, 35 ,55, 80
MAX POWER: 45KW-50KW
WIRE WINDS:
MAX AMP: 500A
ESC: 400A/500A
MAX VOLT: 120V
NO LOAD CURRENT(20v testing voltage): 7A
RESISTANCE (mOhm): .140
SIZE: 154 x 115.54( without shaft )
Stator: 135*50mm
WEIGHT (kg): 5.9
SHAFT: 15mm Accessory pack: Yes
Internal PCB with 120 degree hall effect sensors
http://mymobilemms.com/OFFTHEGRIDWAT...arge-Air-Craft

To find the electric horsepower of a motor, use the equation:
Horsepower = (Volts x Amps) / 745.7
(does not take efficiency into consideration)

Example: The electric horsepower of a motor with 120 volts
and 10 amps is:

HP = (120 x 10) / 745.7

Calculated out this gives an electric horsepower of 1.6092.
(rounded to the nearest 10,000th)
